About this Role
What You'll Do
- Formalize mathematical content from natural language sources — textbooks, research articles, exercises — into valid, compilable Lean 4 code
- Translate theorems, lemmas, propositions, and proofs into precise formal representations
- Ensure formal code accurately captures the mathematical meaning and logical structure of original statements
- Review and validate Lean 4 formalizations for correctness, consistency, and logical soundness
- Identify ambiguities, missing assumptions, or logical gaps in informal mathematical descriptions
- Contribute to high-quality datasets pairing human-written mathematics with formal Lean 4 equivalents for AI training
About the Role
What if your deep knowledge of formal proof and mathematical rigor could directly shape how AI reasons about mathematics? We're looking for Lean 4 experts to translate rigorous mathematical content into machine-verified formal proofs — working at the cutting edge of AI development where automation alone isn't enough. This is a fully remote, flexible contract role built for mathematicians and formal verification specialists who want meaningful, high-impact work on their own schedule.
- Organization: Alignerr
- Type: Hourly Contract
- Location: Remote
- Commitment: Flexible — work at your own pace
Who You Are
- Strong hands-on experience with Lean 4 — you write precise, correct, and maintainable formal proofs
- Solid background in mathematics, formal logic, or formal verification
- Comfortable reading advanced mathematical texts and translating them into formal systems
- Exceptional attention to detail and commitment to logical rigor
- Interested in the intersection of AI, automated reasoning, and mathematical verification
Nice to Have
- Experience with other theorem provers or formal systems (Coq, Isabelle, Agda, etc.)
- Prior involvement in AI training, expert annotation, or reasoning-focused dataset creation
- Familiarity with proof assistants or formal methods research
- Background in academic mathematics or computer science research
Why Join Us
- Work at the frontier of AI — your contributions directly improve how AI models reason about mathematics
- Fully remote and flexible — work from anywhere, entirely on your own schedule
- Clearly defined tasks and evaluation criteria — you always know what success looks like
- Top performers are selected for extended engagements and advanced or leadership tracks
- Join a network of elite mathematicians and specialists solving problems automation can't
Requirements
- Fluent proficiency in English (Written & Verbal)
- Reliable high-speed internet connection
- Bachelor's degree or equivalent professional experience
- Demonstrated expertise in Mathematics

Frequently Asked Questions
What is the assessment actually like?
Notoriously strict. Alignerr uses TestGorilla for role-specific timed tests — a blank coding environment for engineers, rigorous grammar and fact-checking for writers. There is almost no hand-holding. The critical catch: this is essentially a one-shot process. Fail or abandon the assessment, and you are typically locked out of that role permanently with no option to retake.
How quickly can I start earning after I pass?
Not immediately. Even after passing the assessment and completing identity verification (via Persona) and billing setup (via Deel), you may sit in a waiting pool for weeks or months. You only start earning when a project matching your specific skills launches and you are officially assigned. Do not plan around Alignerr income until you are actively on a project.
Is there a community?
Yes — and it is one of Alignerr's genuine strengths. Once assigned to a project, you are added to Slack channels where you can ask questions, get rubric clarifications from admins, and talk to other AI trainers. This is rare in AI training and makes a real difference when guidelines are ambiguous or change mid-project.
Is this traditional consulting?
Not exactly. You act as a "Teacher" for advanced AI. Instead of client deliverables, you are given complex scenarios to evaluate. You grade the AI's logic, correct its hallucinations, and provide expert-level reasoning. Your job is to train the model to think like you do.
Why is the pay so high?
This role requires deep, verified expertise. General knowledge isn't enough; the model is specifically being trained on "edge cases"—the rare, difficult, or highly technical nuances that only a senior professional would know.
What is the workload like?
This is cognitive, deep work. Unlike simple data labeling, you might spend 45-60 minutes on a single task, researching citations or verifying complex calculations. Quality is prioritized over speed.
What is the barrier to entry?
Alignerr is known for difficult technical assessments. You must pass a timed test in your specific domain (e.g., Python, Physics, or Language) before you are eligible for any paid projects.
